Overview: This interactive graph helps students get a visual and understand more effectively how the demand curve shifts graphically and the effect the shifts have on price and quantity. It can be used repeatedly and at any time as a review tool – both by instructors and/or students. This video's running time is less than 30 seconds in length illustrating increase and decrease in demand. It is a simplistic graphic that can be used in conjunction with a lecture on the subject to show the shift and movement of demand.
Learning Goals: • The student will be able to solidify his/her understanding of the shifts in demand curve. • The student will be able to interact and get a visual on how the market equilibrium changes given the changes in the economic variables of the demand.
Target Student Population: • Beginner/Introductory/Survey Economics, Introduction to Macroeconomics, Principles of Macroeconomics, Introduction to Microeconomics, Principles of Microeconomics and/or Business Students • Non-economics or Non-business students taking an Economics and/or Business course as a minor
Prerequisite Knowledge or Skills: • Prior knowledge of the demand curve, and the determinants of demand concepts. • Basic computer skills
Type of Material: Online Interactive Animation
Recommended Uses: • This is useful as a teaching tool to provide a quick visual on how the equilibrium changes with a shift in the demand curve. • The interactive graph can repeatedly serve as a study aid when reviewing the concepts and visualizing the correct solution graphically prior to a test or exam.
Technical Requirements: Browsers: Internet Explorer or Firefox, Flash

Evaluation and Observation

Content Quality

Rating: 4.25 stars
Strengths: The main strength of this animation is that it’s very succinct , clean and clear layout that is not intimidating to students. It is also very intuitive as there is no directions provided, yet one can immediately start using it. The video is very focused to illustrate both increase and decrease shifts in demand.
Concerns: A narrative would be excellent to add to the video to guide the learner through the content. The narrative could be even more effective by using "real world" examples for students to view and think about. It could be augmented with some real life application of the concept provided as exercise questions that are also supplemented with explanations on both the correct and incorrect responses.

Potential Effectiveness as a Teaching Tool

Rating: 4.25 stars
Strengths: Very useful and effective as a teaching tool to show in class on how and when the demand curve shifts, and the final effect the shifts can have on the market equilibrium. This will definitely be one of the ‘Aha’ moments for the students when they can see for themselves the effects on the graph.
Concerns: This could be further improved if the shifts are explained by an example or two of why it can go one way or the other by incorporating the determinants of demand as explanations or examples.

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths: Short and clear visual that can be used frequently and at any time. Very simple to use and navigate using three interactive buttons to increase and decrease demand.

Concerns: It comes with an audio which is more of an annoying noise. Removing it would be very helpful.
